For the sake of the archives, I thought I'd post a couple of more links on this subject to augment Jim's link: Depesz seems to be much respected in the Postgres world and his advice is still considered sound: https://www.depesz.com/2007/07/05/how-to-insert-data-to-database-as-fast-as-possible/ The official docs have a section on this subject too: https://www.postgresql.org/docs/9.6/static/populate.html Note that Postgres has been around for ages (since the 1980s) and so it's easy to find threads with less than up-to-the-minute advice. I'm using the current shipping version, 9.6.3. Version 9.5 added some substantial new features (like INSERT ON CONFLICT) and various optimizations. So, if you're reading this from the future, check out materials that take into account whatever version you're using there. ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
